摘要

The effect of an external resonator on the operation of a single-mode stripes laser bar based on an asymmetric InGaAs/AlGaAs/GaAs heterostructure is studied. It is shown that the external resonator increases the efficiency of optical coupling between bar stripes and to obtain laser generation in a high-order common mode with radiation pattern individual lobes about 1 deg.
